ESTIMATING Your Power Needs

To select the right generator set for the job, determine what equipment you will run individually and simultaneously. Check the wattage requirements on each item (volts x amps = watts). Total the wattages of all equipment to be run simultaneously. Bear in mind that electric motor starting may require up to three times the running power.

The wattages listed below are based on estimated wattage requirements. For exact wattages, check the data plate or operator’s manual of the item you wish to power.

Additional Power Considerations

Some tools and appliances need a “surge” of energy when starting. This means that the amount of electrical power needed to start the tool or appliance may exceed the amount needed to maintain its use. Electrical appliances and tools normally come with a label indicating voltage, cycles/Hz, amperage (amps) and electrical power needed to run the appliance or tool.
